Operation & Process Description:
The Aqua MSBR® USA process incorporates multiple reactor cells to provide a variety of treatment mode alternatives. The design configuration may range from a simple 3-cell configuration that provides oxidation and efficient clarification to a 7-cell configuration that provides enhanced biological nutrient removal. An Aqua MSBR® USA system will include two sequencing cells and a variable number of specific function cells to treat flows beyond 10,000 cubic meters per day.
The Four Phases:
1. Anoxic Mixing and Mixed Liquor Recycle.
2. Aeration, Mixing and Mixed Liquor Recycle.
3. Pre-settle.
4. Clarification.
Features:
• Constant water level.
• Continuous flow.
• Simple operation.
• Adept at processing high-peak hydraulic flows due to storm events.
• Quiescent settling prior to clarification phase.
• Optimized, enhanced biological nutrient removal.
Advantages:
• Small footprint; no separate clarifiers.
• Less equipment to maintain; can be designed to be serviceable without dewatering tanks.
• Fully automated control system.
• Better sludge flocculation; no sludge collection mechanisms.
• Low TSS discharge; effective nitrification, de-nitrification and phosphorus removal.
• Low installation cost.
• Low operating cost.
• Expandability.
